To all whom it 'may concer/a' Be it known that I, HEINRICH KoPPERs, a

citizen of the German Empire, and resident of 30 senbergstrasse, Essenonthe- Ruhr, Germany, have invented certain new and useful Improvements in` or Relating to Gas- Furnaces or Coke-Ovens, of which the fol'- lowing is a specification.

This invention refers to coke furnaces with reversible draft and alternating heating of the separate halves of the walls and is for the purpose of eii'ecting a constant and uniform giving oif of heat tothe furnace chambers, whereby the arrangement and working within the various heating Walls remains the same; but the heating Walls belonging toa furnace are so connected up thatJ vthe gas currents in them alwaysfow in opposite directions Consequently in the section. thelsupply of h'eat to the first half ofthe length of the furnace chamber is veiected from the right' and to the second half from the left; on changing the direction of the draft these conditions are simply reversed. Owing to the slight breadth of the furnace as compared with its length there results a` complete interchange of heat along the same owing to conduction in the charge, thus assuring the `complete uniformity of the heating in each section. A

I shall now describe my invention with reference tothe accompanying drawings in which Figure l is a-diagrammlatic plan view of the arrangement of the regenerators according to the U. S. Patent No. 818033 for the preliminary heating of air constructed according to the invention referred to, and shows the position of the slides and dampers before reversing., Fig. Qshows the same after reversing has taken place. Fig. 3 is a diagrammatic plan of the modification `with a somewhat altered' arrangement of the regenerators. IFi 4 is a cross section through a battery o coke furnaces. Fig. 5 shows the corresponding constructive arrangement in longitudinal-section through the furnace.

The .regenerators are divided into two equal halves and p which have their outlet on both sides through channels r and 1 into the collecting conduits t and u running along the front of the series of regenerators and communicating with the chimneys y and y The channels r and r" can be shut off from the collectingV conduits t and u by' slides /v and fr", Whereas the aircan enter the regenerators through slides lw and w. N ow the slides 'u of the regenerator p and the slides w of the regenerator p are alternately 'shut while the slides fw of p andthe slidesa of pi are alternately open. Thus in the first series of 'regenerators (Fig. 1) the air passes into the one half of the heating walls, supposed to be connected in parallel directly with the regenerators, there itY is burned with the gas suppliedv apart and after passing over into the other half of the heat# ing walls flows into the regenerator p and through channel r and conduit uinto the chimney. The direction of the. current in the second series of regenerators is the very opposite so that the desired distribution of heating is effected. By a suitable alteration of all slides and dampers, which can be simply effected by coupling them up in groups', all the current directions-are reversed (Fig. 2). TheF heating of the furnace chambers,

however, is in no-Wise' varied; as, according,

soy

nogged with ,lattice-Work of fire-proof bricks and are separated from'each other by walls o. The regenerators always communlcate with the adjoining walls Z1 through the air supply passages q, so that the regenerator situated to the right of the heating wall l) communicates with the first group of the heating filles and the regenerator situated to the left with the other group. The channel r beneath each regenerator p communicates with the latter through openings 3 whose clear stions, distributed either uniformly or in accordance with a definite law, taken together give the necessary cross section for assuring a uniform exhaust of the smoke gases as well as a uniform distribution of the air along the whole length of the regenerator. Any cross walls built intol the regeneratorv p for constructive reasons or for regulating the supply are of no importance as regards the individual Working of the regenerator along the whole length of the furnace'. The channels r alternately have their l outlet into the main conduit t on the one `side anduon the other,lfrom which they can ,cocks 7c and nozzles Z into the heating flues ,avoiding any loss of opening the cocks la.

and is there burned with the air which enters the regenerator p through the open damper j and also passes into the heating ilues through the passages q; but the conduit t is shutoff from the chimney y by the damper :11. The exhaust gases fall down into the heating lues of the other side, pass through the second regenerator p and from there into the conduit u which communicates With the chimney y through ,the open damper 12,' but in the heatin Wall situated next to `it the current is in t e opposite direction.

The reversing of the direction of the drafts is effected in regular alteration by closing the dampers 2 and j and opening the ldampers and j-the gascocks c having been previously shut off for purpose of gas-and subsequently If it is desired to cut oli' an individual furnace, this can be directly effected by means of the described slide arrangement `with independence of the individual furnaces obtained by longitudinal division walls in the regenerator. If such Walls are not present the cutting off of the various furnaces can be effected by closing the slide suitably arranged in the heating flues for regulating the draft or by shutting off the passages g. y

What I claim is: In a coke oven, a series of heating chainbers, and coking chambers intermedlate the heating chambers, combied with a series of regenerators below and parallel to the heating chambers, and means for causing the heating gases to flow in" opposite directions in adjoining heating chambers, substantially as specified.

In witness whereof I have hereunto set my handI in presence of -two Witnesses.'
